Dauphin County Emergency Management Agency has assumed responsibility for dispatching Middletown Police.
The transfer occurred at 7 a.m. Wednesday and is expected to save the borough an estimated $300,000 annually.
Middletown had been one of three Dauphin County municipalities that run a local police dispatch, rather than having the county handle the calls.
County spokeswoman Lauren Bowers said the EMA needed no additional personnel or equipment to assume the responsibility.
She reminded Middletown residents to call 911 in case of an emergency. For non-emergency police assistance, residents should still call the Middletown Police Department at 717-948-3000.
